[09/15] aacraid: don't bother with setting SCp.Status

Commit Message

Hannes Reinecke Nov. 25, 2021, 3:10 p.m. UTC

SCp.Status is only ever evaluated to set the return code of
aac_probe_container(), and all callers only check for negative
values here. The callbacks set it to the value of aac_mount.count,
which is an unsigned int; as such it should never become negative
here, and so we only need to return an error from aac_probe_container()
if we can't send the initial fib. But once that's done we can return
'0' and don't need to set SCp.Status at all.
